GPC calibration solution

GPC calibration solutionSystem calibration:

Calibration solution of gel permeation chromatography: a mixed solution containing corn oil (25mg/ml), di (2_diethylhexyl) phthalate (1mg/ml), methoxychlor (200mg/L), pyrene (20mg/L) and sulfur (80mg/L).

Experimental requirements:

gelGPC calibration solutionThe resolution between the chromatographic peaks of corn oil and di (2-ethylhexyl) phthalate is greater than 85%; The resolution between the chromatographic peaks of di (2-ethylhexyl) phthalate and methoxyDDT is greater than 85%; The resolution between the chromatographic peaks of methoxyDDT and pyrene is greater than 85%; The peaks of pyrene and sulfur chromatography should not overlap, and the baseline separation should be greater than 90%.
